Determination of Miliacin from Proso Millet Oil by GC/MS

Proso millet (Pacnicum miliaceum L.) has a various of functional substances, so the demand is increasing as interest in human health benefits. In particular, miliacin, a triterpenoid in proso millet, is known to be effective in hair loss due to its promoting metabolism and proliferation of keratinocytes and showing protective effects from apoptosis. In this study, proso millet oil was extracted and analyzed by GC/MS using the extraction method of unsaponifiable substances after saponification reaction. The components of proso millet oil were confirmed through qualitative analysis by GC/MS. The miliacin content of 5 varieties of proso millet and 2 varieties of foxtail for comparison was analyzed. In the result, components of pentacyclic triterpenes such as β-amyrine and lupeol were detected in proso millet, and the content of miliacin was highest in Hallachal at 370.38±0.04 μg/100 mg oil. In addition, the content of miliacin was not detected in Samdachal and Samdamae, which are varieties of foxtail millet.
